I ordered another BlueRail board Tuesday (got it Thursday, not bad from one coast to the other!!!), got it installed in my WbB E7 Friday. The E7 had been sitting w/o any power in it for over 2 years.
The install included the BlueRail 2amp board, a 9.6v, 2000Mah, NiMh battery pack, on/off switch, charging jack, and 2 LEDs. I mounted the on/off switch thru the window on the rear door of the E7 and drilled a hole thru the door for the charging jack. Painted they're hardly noticeable, with a diaphragm mounted you can't see them unless you're directly behind the engine.
This morning I ran an endurance test on it:
Engine weight = 4lbs. 9oz.
I had it pulling 5 passenger cars:
1) Weaver plastic "American Flyer" (coach converted into a combine) (2lbs)
2) Weaver plastic "American Flyer" coach (2lbs. 1oz.)
3) OK Engines aluminum coach (2lbs. 2 oz.)
4) OK Engines aluminum sleeper (2lbs. 4oz.)
5) OK Engines Sun-Lounge (2lbs. 1oz.)
Combined weight 15lbs. 1oz.
Used the basic setup on the BlueRail App on my Ipad and ran it as a passenger engine at 50% throttle.
I timed the train and it took 1m19s to go 1 mile = 45.5mph
After 2 hours I checked it again and the time was 1m17s = 46.75mph. This is probably the longest the E7 has been run since I bought it!!!
At 2hrs 15m the engine slowed down and stopped, looks like the run time of 2+ hours on a 2000Mah battery is going to about normal, that's about what my Weaver RS3 ran also.
I guess there's no way of signalling when the battery is low??? Best thing is not to leave it unattended and KNOW that 2 to 2.5 hours is average.
No problems encountered during the 2hour+ run.
